Question

Find the volume of the rectangular solids whose dimensions are as follows:
(a) Length = 15 m, Breadth = 12 m and Thickness = 75 cm
(b) Length = $12\frac{1}{2}$ m, Breadth = 5.2 m and Thickness = 80 cm

Answer 1

Given are two sets of dimensions of a rectangular solid.

To find out: Volume of the solid.

$\left(a\right)$ Given dimensions are: $l=15m,b=12m$ and thickness $=75cm$.

Hence, volume of the solid $=l\times b\times \text{thickness}$

$=15\times 12\times 0.75[75cm=0.75m]$

$=180\times 0.75$

$=135m^3$

$\therefore$ Volume of the solid $=135m^3$

$\left(b\right)$ Given dimensions are: $l=12\frac{1}{2}=\frac{25}{2}m,b=5.2m$ and thickness $=80cm=0.80m$.

Hence, volume of solids$=l\times b\times \text{thickness}$

$=\frac{25}{2}\times 5.2\times 0.80$

$=12.5\times 4.16$

$=52m^3$

$\therefore$ Volume of the solid $=52m^3$.
